I must say the 8.8, 14 and the 40 gives views that make you say "WOW". That 40mm SWA is one massive eyepiece (although the 14mm isn't small!). Looking back in the old ads, I did not realize that the 40mm was the most expensive of the Series 4000. I had heard about the 8.8 and the 14 but very little about the 40mm. I really like that big 40mm SWA.
